  1. K-Way Replication Rudrajit Samanta, Thomas Funkhouser, Kai Li Princeton University 2001

  2. 5 step process 2 preprocess steps: - Scene Graph Construction - Object Replication Online/Runtime Steps: - Client Traversal & Assignment - Render & Pixel Composite - Display

  3. Scene Graph • Multiresolution scene graph (from coarse root node to detailed leaf nodes)

  4. - Objects get replicated out to k nodes where k << n. Trying to prevent future starvation (Round Robin Fashion at lowest granularity). - Client has copy of scene graphs, minus polygonal meshes - Client assigns servers to objects per frame using one of two load balancing strategies: Least Server First or Least Cost First/Closest Dot First

  5. - Client assigns servers to viewports for rendering * Servers Render * Servers Perform Peer-to-Peer Pixel Composition - used compression scheme to prevent overworking network ( implemented using interleaving rendering with network sends...other option could be bursts (photonic multicast?)

  6. Display (duh...)
